A lucent femoral lesion was identified on the articular surface of the lateral femoral condyle in four young athletic males. The lesion occurred on the anterior aspect of the lateral femoral condyle just distal to the epiphyseal plate corresponding to the level of the patella. These patients had patellar femoral pain and symptoms consistent with "chondromalacia patellae" or one of the patellar pain syndromes. This femoral lesion has clinical and radiographic manifestations and probably a traumatic etiology similar to osteochondritis dissecans. Radiographically, the femoral lesion is not demonstrated on the routine anteroposterior, tunnel, or skyline views, and it is easily overlooked on the lateral view. The lesion can be identified radiographically on a Merchant view or on fluoroscopic spot films, and it is "hot" on a radionuclide bone scan. Once identified, arthrography and arthrotomography are useful to determine the integrity of the overlying articular cartilage.
在四名年轻男性运动员的外侧股骨髁关节面上发现了一个透亮的股骨病变。该病变位于外侧股骨髁的前侧，恰好在与髌骨水平相对应的骨骺板远端。这些患者有髌股疼痛，症状与“髌骨软化症”或其中一种髌股疼痛综合征相符。这种股骨病变具有临床和影像学表现，病因可能与剥脱性骨软骨炎类似，为创伤性。在常规前后位、隧道位或髌股关节切线位X线片上，股骨病变均未显示，在侧位片上也容易被忽视。在髌股关节轴位片或透视点片上可通过影像学识别该病变，在放射性核素骨扫描上表现为“热区”。一旦识别出该病变，关节造影和关节断层摄影有助于确定上方关节软骨的完整性。
